Microcontroller Based Sine Wave UPS/IPS Technology Sale in Bangladesh.We the leading Embedded system Designer in Bangladesh. 10 Years of Experience in UPS/IPS systems


LCD display for indicating various status of the system like inverter voltage, mains voltage, battery voltage, % of load, overload/short circuit status, battery low status, charger status etc.
LCD based Menu driven setup of various parameters like battery full charge voltage, battery low voltage, load condition, Inverter output voltage, charging current etc.
Protections against: Overload, short circuit, battery deep discharge, battery over charge, mains over voltage, reverse connection of phase in – phase out, reverse connection of phase and neutral of mains input. In all these error conditions will be shown in the LCD display.
Priority solar charging facility: When solar charger is connected mains charger will be in stand-by and priority will be for solar charger.
Delayed inverter cutoff for conditions like battery low, overload, short circuit etc. The system will automatically restart from cutoff after a few second buzzer beeps. The system will go to permenant cutoff if the error condition exists even after 4 restart.
Bill of materials: Main PCB 850VA – Rs. 750/- or less, Transformer 850VA – Rs. 2000/-
1. LCD will display –

Battery voltage
Inverter output voltage
Percentage of load
Mains voltage
Changer on/off
Solar charging /mains charging
Inverter standby on/off
UPS mode / inverter mode
Phase input output reverse : whether mains is connected to inverter output
Neutral and phase reverse : whether neutral and phase is connected reverse
Overload : if load is above 100% and below 300%
Heavy : if load is above 300%
Short circuit
Overload trip
Heavy load trip
Short circuit trip
